Description

TECHNICAL FIELD

The present invention relates to marine vessels and methods of construction therefor, and more particularly, to multi-purpose amphibious support vessels having a plurality of optional operational modular structures for carrying out a variety of missions.

BACKGROUND ART

There are a large number of classes of amphibious ships around the world with each having its basic specialized mission. For example, the U.S. Navy has (LCC) Amphibious Command Ship, (LHA) Amphibious Assault Ship (General Purpose), (LED) Amphibious Assault Ship (Multi-Purpose), (LKA) Amphibious Cargo Ship, (LPA) Amphibious Transport, (LPD) Amphibious Transport Dock, (LPH) Amphibious Assault Ship (Helicopter), (LSD) Dock Landing Ship, and (LST) Tank Landing Ship. Other amphibious ships are used commercially in missions such as Roll On/Roll Off (RO/RO) vehicle carriers, container carriers, and break bulk in open top containers.

The primary drawback of each of the above mentioned vessels is that each class of vessels is optimized for only a single specific mission. Many classes of vessels would be required to fulfill all the possible specific needs. The purchase cost for each vessel can be prohibitive as well as the maintenance and ongoing costs associated with each vessel. A need exists for a single vessel capable of carrying out all of the above described missions, or a selected combination thereof.

Furthermore, typically before construction, each amphibious support vessel must be custom configured depending upon its chosen mission. A need exists for a standardized multi-purpose amphibious support vessel having a standardized hull capable of having a plurality of optional operational structures for carrying out a variety of missions, and capable of receiving a plurality of modular habitable containers for supporting troops and the like. Because of the standardized hull design the optional operational features advantageously can be readily integrated into the vessel so that the vessel will be capable of carrying out a wide variety of operational missions with the optional operational structures selected before the vessel is constructed.

This standardized vessel would be of modular construction with areas of the vessel set aside to receive particular optional desired operational structures. The areas would be spaced apart allowing each of the operational structures to be incorporated into the vessel without interfering with each other.

The standardized amphibious support vessel would also simplify a post-construction modification should the need arise to change the configuration of the vessel for a different mission.

DISCLOSURE OF THE INVENTION

It is, therefore, an object of this invention to overcome to a large extent the above-mentioned needs.

BEST MODE FOR CARRYING OUT THE INVENTION

Referring first to FIGS. 1 a - 1 c and 2 a - 2 b, a multi-purpose amphibious support vessel 30 is depicted which is constructed in accordance with the principles of the present invention. The basic purpose of the vessel 30 is to provide an amphibious support ship which can be constructed to carry out a variety of missions without having to be modified. To accomplish this purpose, as is depicted in the drawings all of the operational structural features can be arranged in the multi-purpose amphibious support vessel independently of each other thereby providing a versatile vessel. Each feature can be incorporated, eliminated or modified at will with a minimum of difficulty and expense.

The multi-purpose amphibious support vessel (MPA) provides for a series of options which can be incorporated into the final design of the MPA ship. The options selected predetermine the range of missions which the MPA can perform without requiring any post-construction modifications. In addition to military missions, the MPA can perform commercial missions such as roll-on/roll-off (RO/RO) vehicle carrier, container carrier, and brake bulk in open top containers. The basic MPA configuration arranges the optional operational structures so that any of the structures, including all of the operational structures can function without interfering with each other.

Referring to FIGS. 1 a - 1 c, the lines drawings of the hull 20 are illustrated. Hull 20 makes extensive use of flat plate sides 22 and flat plate bottom sections 23 to minimize cost. Hull 20 will have the particulars as listed below in Table 1. These particulars are considered exemplary for a ship supporting 500 troops. For Example, if electric power is to be exported to the shore, then an electric propulsion system would be used instead of the geared diesel propulsion system shown. The engine room will be unmanned and designed to the requirements of an owner selected classification society such as the American Bureau of Shipping (ABS).

The detailed description provided below of the multi-purpose amphibious support vessel reflects the operating environment of each of the optional operational structures to be potentially included on the vessel and is not meant to be a full description of each of the structures of the vessel each of which is well known to those of ordinary skill in this art.
